France France canyon rim

Trou de Fer

You can see 11 km from here, looking west.

Calculating the panorama…

Drag to turn around. The relief is drawn 2.2 times taller so the ridges can be read; far ridges are paler, as in the real air.

The view

Up to 11 km away.

Calculated on the relief one degree at a time, up to 250 km, with the curvature of the Earth and the refraction of the air: what stands above the horizon from here.

23out of 100

Our own rating, from the relief and the climate only: open horizon (35 points), how far you see (25), sea and named peaks in view (20) and clear months (20).

The 2 peaks you can name from here

From west to east as you turn around: height, distance and direction. Each one links to its guide on Peakyas, our mountain atlas.

From the relief only: buildings, trees and haze are not in the model. On a hazy day you see much less; 250 km is the limit of our calculation.

The sun

The best sunsets are from August to November.

When the sun really disappears from this viewpoint — behind the relief or into the sea — and in which direction, on the 15th of each month, in local time.

The highlighted months are the clearest. Golden hour starts about an hour before.

The place

Trou de Fer.

Canyon on Reunion Island

On a clear day the farthest ridge you can see is 11 km away, looking west.

2 named peaks rise above the relief in front; the most prominent is Cimandef (2,228 m), 11 km away.

The horizon is open, below your eyes, over 63% of the circle.

The skies are clearest from August to November.
